Tom's Robbsboat

Michalak Robbsboat — 15 ft Pocket Cruiser

Built by Tom Sorenson, This Robbsboat is a Jim Michalak box-boat design inspired by Phil Bolger’s philosophy: simple shapes, real utility, and boats that are meant to be used. Built in 2016 using quality materials, she’s a compact, capable pocket cruiser.

The enclosed “Birdwatcher-style” cabin provides surprising protection and usable space for her size. A central slot keeps the cabin above water even if knocked down, and the interior is large enough to sleep aboard comfortably while staying dry in rain. Ballast comes from batteries, gear, and structure rather than dead weight, giving her a solid feel without excess draft.

She carries a professionally built balanced lug sail on an unstayed mast, making rigging quick and uncomplicated. A leeboard replaces a centerboard, keeping the interior clear and shallow-water friendly. Under power, she’s efficient and easy to move—cruising around 4 knots on roughly 300 watts with an electric outboard, or at modest throttle with a small gas motor.
